It seems the behaviour of the default opener (xdg-open) varies across platforms
and environments. Details are documented in the issue. To prevent an empty file
from being accidentally opened leading to unexpected behaviour, we are adding a
guard with the message that the empty file should be opened using edit or open
option.

Turns out ^B is also intercepted by Windows.

^V does not work while working on Windows. It is intercepted as paste.

Removed file manager and desktop search keys.
Both can be launched with launcher key.
